We believe that everyone deserves access to pure water. With NaDeex, we create the foundation for this.

Clean drinking water, free of pollutants – right in your home.

With the NaDeex reverse osmosis system, you can reliably remove heavy metals, microplastics, and pollutants from your tap water.

What is a reverse osmosis system?

A reverse osmosis system is a state-of-the-art water filtration system that operates on the principle of reverse osmosis. This process uses a semi-permeable membrane to free water from almost all impurities. The water is forced under pressure through an extremely fine membrane that only allows water molecules to pass through, while pollutants, minerals, bacteria, and other undesirable substances are retained.

The result is exceptionally pure drinking water, free from heavy metals, chlorine, pesticides, drug residues, and other contaminants. Reverse osmosis systems are used in both private households and industry and are considered one of the most effective methods of water purification.

The reverse osmosis process is particularly efficient because it can remove up to 99% of dissolved solids from the water. This makes reverse osmosis systems the ideal solution for anyone who places the highest demands on the quality of their drinking water. Modern systems are also energy-efficient and low-maintenance, making them a sustainable investment in health and well-being.

How does reverse osmosis work?

Reverse osmosis works on a simple principle: water is forced under pressure through an extremely fine membrane. This membrane is so dense that only pure water molecules can pass through – pollutants are retained and flushed away.

The process takes place in several stages:

  • Pre-filters remove coarse particles such as sand, rust, and chlorine
  • The osmosis membrane filters out the finest substances such as microplastics, heavy metals, and bacteria
  • Optionally, the water is then mineralized or refined

This multi-stage process produces particularly pure water, free of undesirable substances. Unlike simple filters, the water is not just improved, but completely "reprocessed."

What are the advantages of a reverse osmosis system?

  • Removes up to 99% of all pollutants, microplastics, and pharmaceutical residues
  • Reliably filters heavy metals like lead, copper, and mercury
  • Significantly improves the taste and odor of water
  • Fresh drinking water available at the touch of a button anytime
  • Saves money long-term compared to bottled water
  • Reduces plastic waste and transportation efforts
  • Ideal for families, athletes, and health-conscious households
